To all whom it may concern:

Be it known that I, JAMES P. OCONNELL, a citizen of the United States,residing at Crompton, in the county of Kent and State of Rhode'Island,have invented a new and useful Improvement in Spoofing-Machines, ofwhich the following is a specification.

This invention pertains to new and use ful improvements in spoolingmachines, and the primary object of the same is to provide new, novel,simple and efiicient means to prevent the bobbin over-running itself.

In spooling yarn one of the difficulties which presents itself is thetendency of the bobbin to over-run itself, which results in slack yarnbetween the bobbin and spool, and owing to the twist that there is inthe yarn, kinks are formed, thereby producing a defective yarn on thespool. Further in cases where fine yarn is used the weight of the bobbinWhere the latter is supported in a groove or trough in ordinarystructures commonly employed, the yarn frequently breaks.

The present invention is designed to obviate the difliculties whichordinarily present themselves as above noted, and aims to providea stiicture which is automatic in operation and creates such tension on theyarn as will prevent the slack yarn with its disadvantages specifiedabove.

In the drawings:-Figure 1 is a view in perspective showing the relativeposition of the invention applied to the frame of a spooling machine,the latter being broken away and in partial section, Fig. 2 is a sideelevation of the invention detached from the machine, Fig. 3 is asection on the line 33 of Fig. 2, Fig. 4 is a section on the line 44: ofFig. 2, Fig. 5 is a perspective view of the whirl .frlction retardingmeans, and 6 is a fragmentary perspective view of the friction retardingmeans for the yarn on the bobbin.

In the drawings, 1 designates the upper 10, provided with the whirl 11.Projectingtion 15. The vertical portion of arm 12 is.

formed with a cut-out portion 16, and with a seat 17 ,the shaft 14extending across cutout portion 16 and having a bearing in seat 17.

A brake, preferably formed of wire is constructed to have a shoe 18,formed by looping the wire intermediate its ends, the ends of the loopedportion extending outwardly at right angles to shoe 18, to form arms 19located one above the other, each arm at an intermediate portion beingcoiled as at 20, to provide sockets or eyes for the reception of theshaft 1 1, the wire at the ends of the sockets being extended outwardlyat right angles to the arms 19 to form second arms 21, which have abifurcated weight 22, secured thereto in adjustable manner by means of aset screw 23.

The main brake is preferably formed from a sheet metal blank andcomprises a shoe 24 which is constructed of a double thickness of theblank formed by doubling 01' folding the blank as depicted in Fig. 5,the inner ends of the doubled metal being spread outwardly and mergeinto a socket or eye member 25, which receives shaft 14, so as to havepartial rotation thereabout. An arm 26, formed with a slot '27 iscarried by the main brake, said arm being formed consequently cause thebrake shoes 18 and 24 to engage the bobbin yarn and spindle whirlrespectively.

30 designates an oil duct and reservoir which conveys oil to the spindlebearing,

and 31 designates a stop carried by the holder- 9 to engage the top ofthe. whirl 11 to restrict upward movement of the latter. In operation itwill be observed that the shoe 18 due to the presence of the weight 22maintains a uniform friction on the yarn of the full bobbins. The bentend 15 of the shaft 1 1 is rotatable or adjustable in the extension 13ofthe arm 12, and is held in any position to which it may be adjusted bymeans of a set screw 32. It will thusbe obvious that the projection orend 13 of shaft 14 may be adjusted and held against movement in anypredetermined position to limit the inward movement of the shoe upon 15the yarn of the bobbin, so that aftera predetermined amount of .yarn hasbeen removed from the bobbin, the shoe will notrest on the bobbin andconsequently the yarn will be relieved 'rom that friction exerted by theshoe 18, but'as the bobbin would then be free to over-run itself, thesecond brake which is composed of the Weighted pivoted member carryingshoe 24 is resting on the whirl of the spindle and retarding the freerunning of the latter. Thus at all times regardless ofthe quantity ofthe yarn'on the bobbin, the latter will'be engaged by the brake orretarding means and prevented from over-running itself. Obviously as the3g bobbin grows smaller its speed becomes greater, and the tension onthe yarn'is proportionately increased, which makes it possible todispense with the action of the brake mechanism 18, and to merely employthe brake mechanism 24. Since the welghts are adjustable in eachinstance, it will-be apparclnt that the braking force may be reguate fHaving thus described my invention, I claim as new and desire to secureby Let- 'ters Patent 1. In a spooling machine, in combination v with'the'bobbin, the spindle thereof, and

the spool, a gravity brake for engagement 45 with the bobbin yarn, meansto arrest the movement of said brake at a predetermined period,"and agravity actuated brake in en gagement with the spindle.

2. In a spooling machine, in combination with the bobbin, the spindlethereof, and the spool, a pair of separate and independent adjustabletensiondevices, one for engagement with the yarn on the bobbin, and theother for continuous engagement with the spindle, and means fordiscontinuing the action of one of said devices for a predeterminedperiod.

3. In a spooling machine, in combination with the bobbin, the spindlethereof, and the spool, an arm, a shaft carried by the arm having oneend formed to provide a projection, means whereby said shaft may beadjusted, said shaft being inclined with respect to the spindle,-amember pivoted 65 on said shaft forengagement. with said projectionthereof, said member being formed with a brake shoe at one end to engagethe yarn on the bobbin, a, weight carried by the opposite end ofsaidmember, and a second brake member pivoted to the shaft formed with ashoe to engage. the spindle at one end and carrying a weight at itsopposite end.

a. In a spooling machine, in combination with the bobbin, the spindlethereof, and the spool, an adjustable shaft carrying a Drojection at oneend, a brake mechanism movably mounted on the shaft and having a portionto engage said projection to limit the inward movement of the brake withrespect to the bobbin, and a second brake mechanism movably mounted onthe shaft to engage with the bobbin spindle.

5. In a spooling machine, in combination with the bobbin, the spindlethereof, and the spool, an adjustable shaft carrying a projection at oneend, a brake mechanlsm movable on said shaft and composed of two partsarranged at right angles to each other, one of said parts being formedto provide a brake shoe, a-weight adjustably carried by the other part,said last named part being adapted to engage said projection whereby tolimit the movement of the shoe with respect to the bobbin, a secondbrake mechanism movable on the shaft and composed of two membersarranged at right angles to each other, one of said members forming abrake shoe to engage with the spindle, and the other member. having anadjustable Weight carried thereby.

6.

I 7; In a spoolingmachine, in combination with the bobbin, the spindle thereof, and thespool, a shaft, a brake mounted on the shaft and formed of a section ofsheet metal having two parts-arranged at right an Ice to each other, oneof said parts being fol ed or doubled to provide a brake shoe of twicethe thickness of the metal, an intermediate part of said metal beingbent to form a socket to receive the shaft, and a weight adjustablymounted on the other of said right angular parts.
